Attie is Bluesky's first AI product — a standalone app built on the AT Protocol and powered by Anthropic's Claude that lets users create custom social media feeds in natural language without any coding. Built by Jay Graber (Bluesky's founder) and a new internal "Exploration team", it was unveiled at the ATmosphere conference in late March 2026. The core use case: instead of accepting the algorithm Bluesky gives you, you describe the feed you want in natural language ("show me posts from indie hackers about AI tools, no politics, ranked by engagement") and Attie builds it. Because it runs on AT Protocol, it has access to the full social graph and content signals across all ATProto apps, not just Bluesky. Attie is currently invite-only for ATmosphere attendees, with a public waitlist open. It's already become the most-blocked account on Bluesky other than J.D. Vance — a sign that AI-mediated social feeds are contentious even among the decentralized-web crowd. Future versions will let users vibe-code entire ATProto apps.

Reviewer scorecard
“Using an AI to write your own feed algorithm, on open protocol rails, is fundamentally different from accepting a black-box recommendation system. The AT Protocol data access is the real moat — it gives Claude context no other AI social assistant has. This is the most interesting social AI product in years.”
“No API to speak of. It's a publishing platform, not a developer tool. Built-in audience is the value proposition.”
“Most-blocked account on Bluesky before public beta — the decentralized/open-web community is deeply skeptical of AI-mediated content, and they're not wrong to be. Natural language feed algorithms also sound better than they work; niche interest filtering is still inconsistent. Wait for the waitlist to open and test it yourself.”
“10% revenue share is expensive at scale, but the built-in discovery and reader network provide real value.”
“When users can describe their own feed filters in natural language on open protocol data, the algorithmic chokehold that Twitter and Meta have wielded for years becomes technically obsolete. Attie is early and rough, but it's pointing at the end of platform-controlled content distribution.”
“Every creator hates algorithmic feeds. Attie gives actual control — intent-based filtering instead of opaque engagement optimization. If it works, building a 'show me everything from the 50 creators I care about plus viral design content' feed in five minutes changes social media for creators entirely.”
“The simplest way to start writing and getting paid. The network effect brings readers you wouldn't find elsewhere.”
